Precision measurement of planar double-enveloping hourglass worms

Measurement, 2016
Abstract The measurement of planar double-enveloping hourglass worms has always been a technical problem in the field of gear metrology. To solve this problem, we propose a new method and develop a measuring machine to inspect each deviation of the worms.

Grinding of highly accurate hourglass worm gears — trial manufacture of the worm grinding device

Precision Engineering, 1990
Abstract Highly accurate worm gears can be effectively used as an angle standard. Wildhaber worm gearing is a kind of hourglass worm gearing, which owing to its geometrical simplicity, can have its worm and worm wheel easily finished and accurately measured. This study describes a precision grinding method of the Wildhaber worm. A hobbing machine can

A General Modification Theory for Double-Enveloping Hourglass Worm Drives

Key Engineering Materials, 2011
A universal modification theory is developed for all kinds of hourglass worm drives, no matter what shape the generating surface of the worm is. Based on the theory established, toroidal worm drives can be classified into two main categories: with singular points and without singular points.
